Introduction

This is the Hardware Functional Specification for the RA8876 TFT LCD Controller. RA8876 supports CMOS type interface (MIPI DPI-2). . Including in this document are system block diagrams, Pin information, AC/DC characteristics, each block’s function description, detail register descriptions, and power mode control.

The RA8876 is a low power color LCD Controller with support for up to 512M-bits external SDRAM memory. The RA8876 supports an 8/16-bit asynchronous parallel host bus while providing high performance bandwidth into the external display memory allowing for fast screen updates. The RA8876 also provides support for multiple display buffers, Picture-in-Picture, Opacity control, and display rotation/mirror … etc.
